EASY POINTS!! HELP AND ILL MARK YOU BRAINLIEST!!!!
which of the following points is not on the graph y=-1/2x²-3x+7
(1, 3.5)
(9, -60.5)
(-8 -1)
(6, -30)
Answer: (6, -30)
Step-by-step explanation:
Substitute the points into the equation:
3.5 = -1/2(1^3) - 3(1) + 7 = 3.5: (1, 3.5) is on the graph.
-60.5 = -1/2 (9^2) -3(9) + 7 = -60.5: (9, -60.5) is on the graph.
-1 = -1/2 (-8^2) -3(-8) + 7 = -1. (-8, -1) is on the graph.
-30 = -1/2(6^2) -3(6) + 7 = -29 (6, -30) is not on the graoh.

If each 4 in. on the scale drawing below equals 8 feet, what is the actual area of the shape in square units?
Answer:
the answer is 40 I donk know y
Answer: 384 ft. squared
Step-by-step explanation:
Hey!
So for this problem we first need to convert our scale lengths to feet. Since 4 in. equals 8 ft. that would make the 12 in side 24 ft. long because 12 divided by 4 is 3 and 3 time 8 is 24. We do this because we need to figure out how many times 4 inches are in each length because that how many time the 8ft is in the real length.
Next, we would do the same for the next side and divide 8 by 4 which is 2 and then we multiple 8ft by 2. We then get 16 ft which is our other side length.
After that, we just do our area formula which is length x width or in this case 16 x 24. This gets us 384 and then we add our unit and squared at the end and have our answer.
Hope this helped! :D

Segment HI has a length of 25.3 inches. It can be mapped to segment GO by a reflection over the x-axis followed by a reflection over the y-axis.
What is the length of segment GO
The length of the line segment GO is equal to the line segment HI. Then the length of line segment GO will be 25.3 inches.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
The length of segment HI is 25.3 inches. A reflection over the x-axis followed by a reflection over the y-axis can map it to segment GO.
The size of the line segment will not change when the reflection is taken over the x-axis and y-axis.
Thus, the length of the line segment GO is equal to the line segment HI. Then the length of line segment GO will be 25.3 inches.

1) One baseball team won 20 games throughout their entire season. Of all their games, this
team won 62.5% of them. Given this, how many games in total did this baseball team play
Answer: 32 matches
Step-by-step explanation:
Let the games in total that the baseball team played be represented by x.
Based on the information given in the question, we can form an equation as:
62.5% × x = 20
62.5/100 × x = 20
0.625 × x = 20
0.625x = 20
x = 20/0.625
x = 32
The team played a total of 32 matches.

Simplify the expression and then substitute the given number for the variable. For expression 8a2+6b+9a2+9b2+3b, find the value if a=2,b=−1.
Answer: 68
Step-by-step explanation:
Simplifying the expression:
= 8a² + 6b + 9a² + 9b² + 3b
Collect like terms
= 8a² + 9a² + 6b + 3b + 9b²
= 17a² + 9b + 9b²
We then substitute a=2,b=−1.
= 17a² + 9b + 9b²
= 17(2)² + 9(-1) + 9(-1)²
= 68 -9 + 9
= 68
Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1
Answer:
A) [tex]x = y^{2}[/tex]
Step-by-step explanation:
An equation is a function of [tex]x[/tex] when [tex]x[/tex] is the independent variable, that is:
[tex]y = f(x)[/tex] (1)
Where [tex]y[/tex] is the dependent variable.
According to this, [tex]x = y^{2}[/tex] does not represent a function of [tex]x[/tex], since the independent variable is a function of [tex]y[/tex], that is, [tex]x = f(y)[/tex]. Therefore, the correct answer is A.
